Acoustic scattering from sand dollars (Dendraster excentricus) : modeling as high aspect ratio oblate objects and comparison to experiment
… angle penetration of the seafloor. Sand dollars (Dendraster excentricus) occur commonly in the ocean and have been shown to be significant scatters of sound. In order to understand more fully the scattering mechanisms of these organisms, the scattering from individual sand dollars was studied …

Ingestion Rates of Five Species of Pacific Northwest Echinoderm Larvae on Natural and Artificial Particles
… purpuratus, and the sand dollar Dendraster excentricus, were investigated by assigning larvae to three natural and one artificial diet in the laboratory. The natural algal diets included Dunaliella tertiolecta, Isochrysis galbana and Rhodomonas sp. The artificial diet used was a …
